#### Topic: How to show the maximum value taking into account dates?

There is a table with value and date

``````CREATE TABLE IF NOT EXISTS ` table ` (
` name ` varchar (11) NOT NULL;
` price ` varchar (11) NOT NULL;
` dt ` datetime NOT NULL
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
INSERT INTO ` table ` (` name `, ` price `, ` dt `) VALUES
(' tampo ', ' 6 ', ' 2017-09-26 3:50:00 PM ');
(' tampo ', ' 7 ', ' 2017-09-26 3:51:00 PM ');
(' tampo ', ' 4 ', ' 2017-09-26 3:52:00 PM ');
(' tampo ', ' 5 ', ' 2017-09-26 3:53:00 PM ');
(' tampo ', ' 1 ', ' 2017-09-26 3:54:00 PM ');``````

How to show 2 or more lines as reduction of the price but taking into account time.
I turn out I want to receive such output here:
' tampo ', ' 7 ', ' 2017-09-26 3:51:00 PM'
' tampo ', ' 5 ', ' 2017-09-26 3:53:00 PM'
' tampo ', ' 1 ', ' 2017-09-26 3:54:00 PM ' (not mandatory)

ORDER BY

If you mean request of type:

``````SELECT * FROM table
ORDER BY ` price ` DESC, ` dt ` ASC``````

That it does not approach, as at first shows sorting according to the price, and then all dates.
It is necessary to me that it showed those dates which more than were

. Why result 7-5-1, instead of 7-4-1, 6-5-1 or 6-4-1?

We sort by the price, we receive 7 6 5 4 1:
+ 7 ceiling price with it also we begin
- 6 does not approach, as date is less than at 7
+ 5 approaches, time is more to that 7
- 4 does not approach, as date is less than at 5
+ 1 approaches, time is more than at 5

... Here LEAD/LAG are not implemented. An optimum  -  and the cursor in it.

...Well "sql variables" give a lead/log, but agree,
To the beginner it is better on stored-procedure....
